Hi folks!
I started MSAVR project 11.4.2004. Goal is to get old Opel 18E engine running with MS. My MegaSquirtAVR project pages in finnish. http://kotisivu.dnainternet.net/sakrkorh/
Update 30.4.2004
New pictures from my homemade board.
Update 8.5.2004
IT'S ALIVE!!
Got my engine running with MSAVR. Engine is running pretty rich. At the end of my project page there are my current Megatune config. Comment here freely.
Update 11.6.2004
Web pages moved to new server. New pictures added.
Selfmade casing
20.6.2004
Got Opel Ascona frame but the engine was small block and gearbox doesn't fit to my 18E. Stripped some elektronic from frame.
Need info for GM MAP sensor part no. 834 8298.
Not sure of type, but all 1.15 kPa MAP sensors I've seen from GM were
- A: GND (this is the rightmost pin, when looking at it natural orienation - as mounted on the firewall input nipple pointing down; not leftmost)
- B: MAP signal
- C: +5V (from EC36 Hall supply)
2.8.2004
I got order to make another GenBoard2.2. PCB is ready and part order is done. Boards are now spreading in Finland. :)

My cylinder head suffered little damage, so my FI-project freezed. Trying find info to use Genboard ver2.2 to control ignition via standart GM distributor and dwell-control-module. I didn't find any info how to set my settings right and installation when I use this kind on setup. Module is Bosch 1 227 022 008.
I copy-paste from MembersPage/ChrisGerhardt :
I am using the existing ingition amp. The amp is wired with Signal(DB37 pin12), VCC, GND, and a 270ohm resistor between VCC and Signal. After some searching I found that this is a typical GM module that Edelbrock packaged "nicely" in Edlebrock case. The module fires on falling edge and does not control dwell time. I am using MSAVR for that.
I checked edis.c and found that
ign_activate() and ign_deactivate() functions switch IGN_PORT &= ~_BV(IGN_OUT); which is PORTB7 by default.
After searching (without result), you can probably find (or create) the right place for this info, definitely not good on memberspage (it should be on common page and memberspage should only link to it). Candidates: DummyIgnition DwellControlIgnition or somewhere else near IgnitionPage
- I connect signal from hall sensor to my recent coil input on MS(pin6)? Almost: check what mods Chris made to get the low level signal reliably to the AVR: he even has pictures (bypass the optocoupler altogether, IIRC).
- Take misc output(pin12) to my ignition module. (yes! Check if pullup to 5V is needed - ign modules usually have it internally) * No firmware changes required (use vanilla v2 firmware), just appropriate config

Got ignition working in bench, and squirt is now ready to install into car. Can I use megatune program with somekind of settings.ini file so it understands Genboard ignition map?
A: We are currently working on a .ini-file for megatune to work with all the options, until this is done, you can use the MSNS(megasquirt'n'spark) compatibility mode, OtherTuningSoftware/MegaTuneMSNS //Emil
I hammered current CVS firmware to support Genboard 2.2. Everything should work fine (it was many minor issues, like HWMAP not defined vor v2), but please do some table-testing if possible. - Marcell

Car is now running with my own ignition. I have tiny problem with signal interface. I get false triggers when engine is idling. Some times it gets about 2200 rpm signal when engine is running at 800rpm. Here is my interface.
Can you link more info about this HEI? (to a dedicated page if possible).
I didn't found any info for this ignition module. I don't even know if it is HEI. It has 6 pins, case is ground, it is similar to GM 7-pin HEI module.
Pins are marked: P and N are for inductive coil sensor. O is signal output. I is input. C is to ignition coil negative terminal and + is operating voltage.
Module is in AC DELCO distributor, GM logo printed in case. It is used in OPEL 16SV engine. It communicates with Siemens made ignition control box. Box has own map sensor.
You can find few poor quality pictures at the end of my project diary.
I've seen false triggering
- when getting signal from (alien ignition) igncoil primary using falling edge (instead of rising). Not the case here as I understand.
- bad ground or insufficient shield
shielding might be my problem.

Ok, solved my compile problems with all firmware versions. WinAVR 20050214 has some major changes I think (PGM_RDB errors). I downgraded to 20040720 and all is working again.
25.2.2005
What is today the best tuneprogram for ver2.2? I tried to tweak MegaTune with vemsv3.ini file but configs doesn't work very well and loaded tables are rubbish.
Also tried megatunix for windows, but it reagonizes my genboard as Detected Firmware: Standard Bowling & Grippo v2.0-3.01. Can I make it reagonize my board correctly and if it does it somehow can I use it to tune all my config settings?

Made cleanup for this page. Added MembersPage/SamiKorhonen/History and MembersPage/SamiKorhonen/NewFirmwaretoVerTwo
